Abstract
Emission spectroscopy of nanometric material systems is an important application of the optical near field (see Sect. 3.3.2), in which emission spectra are measured by a probe brought close enough to the light-emitting object. The present chapter aims to investigate the basic spectral properties of a single atom or molecule as the nanometric material system. If a conducting or dielectric probe approaches the nanomaterial, the emission properties of the atom or molecule are substantially modified. This phenomenon is discussed by treating the atom or molecule as an oscillating electric dipole moment. After presenting the basic concepts in Sect. 5.1, Sect. 5.2 gives an analytical method in which the probe tip is approximated as a planar mirror. The results of a quantum mechanical approach are described in Sect. 5.3.
